Mr. Guo is a teacher from Xi’an. He asked his students to hand in their homework through a QRcode (二维码). “We spent an hour or two in class learning how to generate (使产生) the codes, and in the end everything gets easier,” said Guo. “When students finish the homework, they keep it on WeChat. Then, each student makes his own QR code and gives it to me. So I can check their homework everywhere using my computer or telephone.”
The QR codes can be sent to Mr Guo by email, QQ and WeChat When Guo scans (扫描) his students’ QR codes, their homework appears on his phone. He finds that their homework becomes more creative, with many pictures, music and even videos.
Guo’s students like the new way and think it is interesting. “We are living in the information age. Many students like to work with computers, which makes learning more fun.” said Tingting, a student of Guo’s.
“The paper is not easy to keep, but the code is easy to keep and share.” Guo said, “It is worth trying to use new technology in education. Education itself is a kind of creation. I don’t want my students to fall behind the times.”
However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it’s unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the code when they hand in their homework, which doesn’t take them too much time. Also for teachers it allows them to check the students’ homework at any time. And it’s also an easy way to share homework with other students.

【推荐1】(Science and technology makes our school life easier and better than before! When your teacher gives lessons with his phone or iPad, Bluetooth does help a lot. What is Bluetooth? Read the article and find it out!)
If you look around the room you are in right now, you’ll probably notice a number of electronics. But can you imagine if they all had to be joined together by wires (电线)? Picture the wire snaking along the floor, for example, from your smartphone to your speaker, or connecting your game controller to the computer screen, meaning you could never sit more than a couple of meters away from it. A world of electronics connected by wires wouldn’t just be untidy, but a possible danger, too. That’s where Bluetooth comes in. We’ve all heard of it—but what exactly is it?
Bluetooth is a method of short-distance(短距离)wireless communication between electronics that makes use of the power of radio waves. The idea was first thought of by Dr. Janp Haartsen at Swedish mobile company Ericsson in 1994. Things really stepped up in September 1998 when the Bluetooth Special Interest Group(SIG) was set up to develop and spread the technology. Bluetooth 1.0 came out in 1999, and a year later it began to be used in mobile phones and desktop computers. Now Bluetooth has become an increasingly popular way of solving the problem of more and more electronics needing to be connected without having to connect everything together with wires.
But if you look at the remote control(遥控器)you use to choose the program on TV, you might rightly ask yourself why Bluetooth was such a big deal. After all, connecting objects with infrared signals(红外信号)which can’t be seen had been done before. The problem with remote controls is that they need to keep what is called “line of sight”. If something is standing between the remote control and receiver, it won’t work. Because Bluetooth uses radio waves, the things standing in the way are no longer a problem.
Since its creation in the late 1990s, the technology has become more and more improved and widely used, with the 4 billionth Bluetooth objects shipped in 2020.
1. How does the writer lead in the topic “Bluetooth” in Paragraph 1?A.By describing scenes. | B.By comparing facts. |
C.By telling stories. | D.By explaining reasons. |
A.started to be used in cars | B.made radio waves known to people |

【推荐2】Aren’t mobile phone, e-mail and voice mail supposed to help us communicate more easily? Sadly, that’s not always the case. Take the other day for example: when I was walking through the park with my friend, suddenly his mobile phone rang and he answered it—leaving me alone and cutting our conversation dead! In fact, the park was filled with people talking on their mobile phones. They were passing other people without even looking at them, or stopping to walk their dogs. Clearly, people can use mobile phones everywhere, but they ignore the people around.
Why is it that the more connected we get, the more disconnected I feel? New communication technology seems to keep away from each other. With e-mail over the Internet, we can communicate without seeing or talking to one another. With WeChat or QQ, you can have conversations without even meeting that person. Even some food stores are using self-scanners so that you can check yourself out. As the contact between human beings becomes automated, my feeling of being disconnected gets stronger. Don’t get me wrong. I’m not against machines. I also own a mobile phone, a QQ, a WeChat and an e-mail account. Giving them up isn’t a good idea, as they are useful to have around. It’s just that when they keep us away from human contact, I begin to feel sad. Moreover, I find myself answering e-mail instead of talking to people. The technology that was made to help keep us in contact with each other is, in fact, making me feel more lonely.
What is to be done? Well, try to use less technology: no e-mailing people who live nearby, and no letting QQ and WeChat catch you all the time.

【推荐1】All through grade school, I got extra help with schoolwork. If I got a D, I was very happy. If I got a C-minus (C-), I had achieved greatness. A’s and B’s were a kingdom I could never enter.
Once my teacher, Miss Mills, had given me a list of ten spelling words. My mother and I went over the list until I knew those words. I felt great. I thought, “Wow! This time, I’m going to pass.” The next day, I went into the classroom and began to write down the words. The first word was carpet. I wrote that one down: c-a-r-p-e-t. I was feeling pretty confident. Then came neighbor-I wrote down the letter n. Then rhythm-I knew there was an r. Suburban-I wrote s-u-b. My confidence failed me. I had gone from 100 percent to maybe a D-minus. Where did the words go?
Some people talk about information sliding off your brain. That was my life. I was an underachiever (未能充分发挥学习潜力者).
Now I know I have dyslexia (诵读困难症). A person with dyslexia might see the as teh, and bird as brid. My brain learns differently. A learning disability can really change the way you feel about yourself. Now I know that even if I learn differently, I can still be filled with greatness.
Today when I visit schools as an actor, director, and co-author of children’s books, I tell children that everyone has something special inside. It’s our job to find out what that is and get it out, and give it to the world as a gift.

【推荐2】Shylock held his knife and told Antonio to get ready. “Wait!” said Portia. “You will not do anything that is not written in the contract (合同). Is that right, Shylock?”
“Yes, that’s right,” said Shylock. He wondered what the wise young judge was going to say.
“Well,” said the young judge, “I have read the contract carefully, and it does not say anything about taking his blood. It says ‘a pound of flesh (肉)’. You can take your pound of flesh, but you may not take one drop of his blood. If you take any of his blood, the duke (公爵) will take everything you own.”
Now it was Graziano’s turn to praise the judge and call him wise. “Did you hear that, Shylock?” he asked. “What a wise judge!”
“You wanted justice (公正),” Portia told Shylock, “and you will have it. You will have more justice than you wanted.”
Shylock didn’t want to give everything he owned to the duke. He decided not to take his pound of flesh. He said he would take the money. “Give me ninety thousand dollars,” he said, “and I will have pity on Antonio and let him go.”
Bassanio was happy to give him the money. “Here it is,” he said. “I have it ready for you.” He was very pleased that his friend Antonio would not die.
“Wait!” Portia said again. “He does not want the money. It is not written in the contract, and he said he would not do anything that was not written in the contract. Shylock, you can take your pound of flesh, just as the contract says. Why are you waiting?”
Shylock said he just wanted to have his money back. “Just give me the money I lent you. I won’t even ask for interest,” he said. Bassanio was ready to give it to him, but again Portia stopped him. “He said he wanted only the penalty that is in the contract.”
Shylock understood that he would not get his pound of flesh. He understood he would not get his money. He decided to go home.
“Wait!” said Portia, for the third time, “The law of Venice says that if you plan to kill a citizen of Venice, you will lose everything that you own. Half of what you have will belong to the person you tried to kill, and the other half will belong to the duke.”

【推荐3】Nate suffered a hard blow when he lost his job. His boss had spoken rudely, “Your services are no longer needed.” Nate left the building filled with despair. By the time he reached home, he was in a deep depression. When he entered his house, he blurted out to his wife Sophia, “I lost my job. I am a complete, absolute failure.” A tense silence followed. Then a smile crept across Sophia’s face. “What great news!” she responded, “Now you can write the book you have always wanted to write.”
“But I have no job and no prospect of a job,” he objected, completely without hope. “If I struggle to be an author, then what will we live on? Where will the money come from?” Sophia took her husband by the hand and led him to the kitchen. Opening a drawer, she took out a box that was full of cash. “Where on earth did you get this?” Nate gasped. “To whom does it belong?”
“It’s ours!” Sophia replied. “I always know that one day you would become a great writer only if you were given the chance. From the money you gave me for housekeeping every week, I have saved as much as I could so you would have your chance. Now there is enough to last us a whole year.”
What a surprise! What encouragement! What a wife! The unemployed husband did concentrate on writing that year, and the novel he wrote became a literary masterpiece(杰作).

【推荐1】“I sometimes get up at three or four in the morning and I surf the net.”
“I often check my email 40 times a day.”
“I often spend more than three hours at one time on the net.”
“I spend more time in chat rooms than with my ‘real-life’ friends.”
Do you know any people like this? They are part of a new addiction(瘾) called Internet addiction. Internet addicts(成瘾的人) spend at least 30-40 hours online every week. The use of the Internet can be an addiction like drug(毒品) use. People lose the control of the time they spend on the Internet.
For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he had been surfing the net for several days.
Studies show that about 6 percent to 10 percent of Internet users become addicted. And people worry about the teens because the Internet is changing the playing field for some of them. They spend more time in cyberspace than in the real world with friends and family.
Is “surfing the net” a hobby or an addiction for you? You may have a problem if you have these symptoms(症状):
You do not go to important family activities or you do not do schoolwork because you like to spend hours on the Internet.
You can’t wait for your next online time.

【推荐2】A black hole is a place in outer space with very strong gravity. Gravity is a great force(力量) that shapes the universe. On Earth, gravity makes apples fall from trees. It keeps your feet planted on the ground. The gravity in a black hole is much stronger. It is so strong that nothing around it can get away from it, not even light.
Black holes are invisible. We can’t actually see them because they don't throw back light. But scientists can find them with space telescopes(望远镜)and special tools. The strong gravity makes nearby stars move in a certain way. By studying how the stars move, scientists can find out if they are flying around a black hole. Strange things happen around black holes. This makes black holes a popular subject of science fiction(科幻)stories, although they are very real.
A black hole forms when a star dies. The star falls in on itself and turns into a very small point. Because of its small size and huge mass(质量), the gravity will be so strong that it will pull light in and become a black hole. Black holes can grow huge as they continue to pull other things in and “eat” them. Many scientists believe that there are super-massive black holes at the center of galaxies, including the Milky Way.
The idea of the black hole was first suggested by two different scientists in the 18th century: John Michelle and Pierre-Simon Laplace. In 1967, a physicist named John Archibald Wheeler came up with the name “black hole”. Studying black holes can tell us many things about our galaxy and help scientists answer questions about the universe.

Thomas Edison was born in America. He invented plenty of electric appliances(电器) and people from all over the world know him. At that time, there was no electric lamp in the world. And it brought people much trouble. Young Edison decided to invent it. He didn’t know which material was suited to be a lamp filament(灯丝). He failed and failed and he spent a lot of time on it. Some of his friends asked him to stop the experiments, but he didn’t listen to them and tried his best to find the material.
One afternoon, one of his friends came to visit him, he was doing his experiments in the lab when the man came in. But he only asked his friend to sit down and didn’t stop to talk with him. The man sat for a long time and Edison said nothing to him. His friend was angry with him and said, “You’ve done the experiments 1,200 times but you failed 1,200 times too!”

【推荐1】Do you have a smart speaker to play your favorite song? Have you ever had a chat with Siri? I'm sure your answer must be yes. Voice assistants are programs on digital devices. They listen and respond to verbal (口头的) orders.
Today's voice assistants can help you with many things. They can do almost anything you can think of. They can answer questions, make calls as well as provide weather, traffic, sports and other realtime information. They can even control smart devices (装置) in your home, such as the highlights and air conditioner.
So how do they understand us?
It all starts with a signal word. Users say the names of their voice assistants to get their attention. For example, they might say, "Hey, Siri!" The signal word wakes up the device and tells it to begin paying attention.
After it hears the signal word, the voice assistant starts recording. The device waits for a pause to know you've finished your request. It then sends your recorded request over the Internet to its database (数据库).
Once in the database, your request is compared to other requests. It's divided into separate orders that your voice assistant can understand. The database then sends these separate orders back to the device. When it receives the orders, the voice assistant will carry out the task you asked for.
Voice assistants are improving all the time. If you say to a smart speaker, "Play rock music", and it plays country music, you'll tell it to stop. This teaches the device that the orders it received from its database were wrong. It will tell the database about the mistake and try to do better next time.Sometimes a voice assistant might ask a question after it receives your request to make sure it understands what you want.

Should we be afraid of sharks? Maybe not. New research into the reasons for shark attacks(攻击)suggests that sharks don't like the way humans taste! In fact, most people who are attacked by the shark are still alive after receiving only one bite(咬). Why is this?
There are many opinions to explain why sharks sometimes attack people. One opinion is that sharks are just curious. We know that sharks are the strongest animals in their environment, so they are not afraid of anything. Naturally, that means they are curious when they meet something unusual. Because they don’t have hands or feet, the only way they can find out an object is to bite it! It is thought that sharks sometimes bite humans for this reason, and then swim away.
Scientists also say that sharks would not waste energy trying to eat a human, as we have a lot of bones (骨头). It is hard for a shark to eat us because sharks don’t have hands, and they can't pull the meat off our bones. Maybe that's why they only bite us once. Unluckily, one bite from a large shark is serious enough to hurt people greatly!
Another opinion is that sharks attack humans by mistake. Some sharks may sometimes mistake humans for seals. An example of this is when a shark attacks a surfer. A surfer lying on a surfboard looks like a seal when seen from below. Sharks like seals because they have thick fat.
Whatever the reason for shark attacks on humans, sharks should be afraid of us. Sadly, we kill almost 40 million of them each year.
